x=2

10-2(2x+1)=4(x-2)

10-4x-2=4x-8

10-2=8x-8

8=8x-8

16=8x

Answer:

X = 2

Step-by-step explanation:

\sf \: First, solve  \: the \:  brackets.

\sf \: 10 - 2(2x + 1) = 4(x - 2) \\  \sf10 - 4x - 2 = 4x - 8 \:  \:  \:  \:  \:  \:  \:

\sf \: Combine  \: like \:  terms .

\sf8 - 4x = 4x - 8

\sf \: Subtract  \: 4x \:  from \:  both  \: sides \:  to  \: remove \:  4x.

\sf \: 8 - 4x - 4x = 4x - 8 - 4x \\  \sf8 - 8x =  - 8

\sf \: Subtract  \: 8 \:  from  \: both \:  sides \:  to  \: remove \:  8.

\sf8 - 8 - 8x =  - 8 - 8 \\  \sf - 8x =  - 16

\sf \: Divide  \: both  \: sides \:  by \:  -8.

\sf \: x = 2

Find a cubic polynomial in standard form with real​ coefficients, having the zeros 4 and 5i. Let the leading coefficient be 1.
SCORPION-xisa [38]
If one of our zeros is 4, then the factor is x-4.  If the second zero is 5i, then the conjugate root theorem says there HAS to be a root that is -5i.  So our 3 factors are (x-4)(x+5i)(x-5i).  We will FOIL out these factors to get the polynomial.  Let's start with the ones that contain the imaginary numbers.  Doing that mutliplication we get x^2-25i^2.  i^2 is equal to -1, so what that expression simplifies down to is x^{2} +25.  Now we will multiply in that last factor of (x-4):  (x^2+25)(x-4).  FOILing out we have x^3-4x^2+25x-100.  There you go!

Explain how finding 7×20 is similar to finding 7×2000 then find each product
AURORKA [14]
You will get the same answers but with more zeros. For example 7x20 is 140, and 7x2000 is 14,000 but with more zero's

The product of the slopes of perpendicular lines is -1. Which function represents a line that is perpendicular to y = -6x + 7
Svetllana [295]
Y= 1/6 x + 7. To find a line that is perpendicular just take the slope and find the negative reciprocal. ex. A/B becomes -B/A. Hope this helped

a landscaper has 125 tiles it has to be a square patio , the patio has to have at least an area of 80 square feet what are the p
Marat540 [252]
Area of a square is given by multiplying the length by the width, but since a square has four sides of equal length, we will end up multiplying two numbers that are the same.

We want a minimum area of 80 square feet and at the maximum of 125 square feet

Think of the square numbers that are in between 80 and 125

8 × 8 = 64
9 × 9 = 81
10 × 10 = 100
11 × 11 = 121
12 × 12 = 144

There are three possible measurements of the patio:

9 by 9 and number of tiles left = 125 - 81 = 44 tiles
10 by 10 and number of tiles left = 125 - 100 = 25 tiles
11 by 11 and number of tiles left = 125 - 121 = 4 tiles
